Merge XLT Files

Introduction

In this tutorial, we’ll explore how to merge XLT (Excel Template) files. GroupDocs.Merger is a powerful API that allows developers to manipulate various document formats, including Excel files, programmatically. By merging XLT files, you can combine multiple templates into a single document, streamlining your workflow and enhancing efficiency.

Prerequisites

Before we begin, ensure you have the following prerequisites:

  1. GroupDocs.Merger for .NET: You can download the API from here.
  2. Development Environment: Install Visual Studio or any compatible IDE.
  3. Basic Knowledge of C#: Familiarity with C# programming language and .NET development.

Import Namespaces

To get started, import the necessary namespaces in your C# project:

using System; 
using GroupDocs.Merger;
using System.IO;

Step 1: Set Up the Output Directory

Begin by defining an output directory where the merged XLT file will be saved. Replace "Your Output Directory" with your desired path.

string outputFolder = "Your Output Directory";

Step 2: Define the Output File Path

Specify the name and path for the merged XLT file within the output directory.

string outputFile = Path.Combine(outputFolder, "merged.xlt");

Step 3: Load and Merge XLT Files

Utilize GroupDocs.Merger to load and merge the source XLT files. Here, we’ll demonstrate merging two XLT files.

// Load the source XLT file
using (var merger = new GroupDocs.Merger.Merger("Your Sample File"))
{
    // Add another XLT file to merge
    merger.Join("Your Sample File");
    // Merge XLT files and save result
    merger.Save(outputFile);
}
Console.WriteLine("\nXLT files merge completed successfully. \nCheck output in {0}", outputFolder);

In this code snippet:

  • "Your Sample File" and "Your Sample File" represent paths to the source XLT files.
  • merger.Join() is used to add another XLT file for merging.
  • merger.Save() is called to merge the XLT files and save the result to the specified outputFile.

Conclusion

In this tutorial, we’ve explored how to merge XLT files. By following these steps, you can efficiently combine multiple Excel templates into a unified document, enhancing document management capabilities within your .NET applications.
